主要介绍了从MySQL的源码剖析Innodb buffer的命中率计算,作者结合C语言写的算法来分析innodb buffer hit Ratios,需要的朋友可以参考下

按官方手册推荐Innodb buffer Hit Ratios的计算是:   100-((iReads / iReadRequests)*100) iReads : mysql->status->Innodb_buffer_pool_reads iReadRequests: mysql->status->Innodb_buffer_pool_read_requests 出处: http://dev.mysql.com/doc/mysql-monitor/2.0/en
